"Reese Witherspoon and beau Jake Gyllenhaal take her kids, Ava, 9, and Deacon, 5, to the Elton John and Billy Joel concert held on Saturday night (August 1) at Citizens Bank Park in Philadelphia, Penn.
Deacon had the best view in the house, sitting stop Jake’s shoulders. 
During the 3-1/2 hour show, Elton dedicated the song “Tiny Dancer” to Reese, saying, “Reese, this one’s for you, girl.”
The happy family danced to “Crocodile Rock” with Reese and Jake bumping their hips together.

(One quick note on celebrity, it must suck sometimes. Every single person in a 30 feet radius was taking photos and staring . At first I just naturally assumed they were all readers of my blog, so I just kept waving and waving. Not. Reese Witherspoon’s kids were so crazy cute. And those two seem like really great parents to those kids. Particularly Jake Gyllenhaal who spent most of the concert with Reese’s son on his shoulders.)"
